Thus if you are 2464 running a MIPS32 system and know that none of your userland binaries 2465 will require 64-bit floating point, you may wish to reduce the size 2466 of your kernel & potentially improve FP emulation performance by 2467 saying N here. 2468 2469 Although binutils currently supports use of this flag the details 2470 concerning its effect upon the O32 ABI in userland are still being 2471 worked on. In order to avoid userland becoming dependant upon current 2472 behaviour before the details have been finalised, this option should 2473 be considered experimental and only enabled by those working upon 2474 said details. 2475 2476 If unsure, say N. 2477 2478config USE_OF 2479 bool 2480 select OF 2481 select OF_EARLY_FLATTREE 2482 select IRQ_DOMAIN 2483 2484endmenu 2485 2486config LOCKDEP_SUPPORT 2487 bool 2488 default y 2489 2490config STACKTRACE_SUPPORT 2491 bool 2492 default y 2493 2494source "init/Kconfig" 2495 2496source "kernel/Kconfig.freezer" 2497 2498menu "Bus options (PCI, PCMCIA, EISA, ISA, TC)" 2499 2500config HW_HAS_EISA 2501 bool 2502config HW_HAS_PCI 2503 bool 2504 2505config PCI 2506 bool "Support for PCI controller" 2507 depends on HW_HAS_PCI 2508 select PCI_DOMAINS 2509 select NO_GENERIC_PCI_IOPORT_MAP 2510 help 2511 Find out whether you have a PCI motherboard.
